Be it known that I, WILLIAM DALTON, o

Schenectady, inthe county of Schenectady u and State of New York, have invented a certainnew and useful Improvement in Electrio-Motor Trucks, of which improvement the following is a specification.

My present invention relates to trucks for electric-motor cars; andits object is to provide a truck of such class in which the number of'boltconnections used shall be reduced as far as practicable and in which they shall .be so disposed. as to avoid liablhty ofinjury to .the truck by bolts working loose and not to necessitate close and perfectworkmanship .My invention is also designed to afford improved facilities for the support ofthe motor and of the brake-rigging.

The improvement claimed is hereinafter fully set-forth.

In the accom anying drawings, Figure 1 is i a side view ine evation of an electric-motor truck embodying my invention; Fig- 2, a half plan or top view of the same; Fig. 3, a transverse central section; Fig. 4, a section, onafn enlarged scale, through theaipper portion of oneof the transoms' and a connected motor-support; Fig. '5, a front view of the "same; Fig. 6, a section through one of the wheels and its driving-gear; Fig. 7, aplan view of one of. the brake-lever connections; Fig. 8, a side view of the same, and Fig. 9a transverse section.

In the practice of m invention, I provide a truck-frame, each 0 the side members of whlch is formed in an integral casting or forging comprising a top bar 1, pairs of pedestal-jaws 1*, projecting downwardly therefrom, a bottom bar 1 connecting the two innor. pedestal- 'aws or those nearer the middle of the true vertical outwardly-flanged transom-posts 1", connecting the top and bottom bars adjacent to the transverse central plane of the truck, inner diagonal braces 1, extending from the top bar to the bottom bar between the transom-posts and the inner pedestal-jaws, and end diagcmal-braccs 1",

extending from the to bar to the lower ends of the outer .pedesta -jaws. The diagonal bracesl transmit the strains from the sides of the axle-box sprin s directly to the middle of the trussed side frame member, the

truck as to admit between them the bolster 1() and bolster-springs 5. The upper flanges of the transoms are connected by brace-laws 9 widened at their ends and recessed on thciix" lower sides, so as to bclippr-d ovcrthetop bars of the side frame members, to whici they are connected by bolts 9, which by reason of the engagement of the. recesses of the upper flanges with the top bars are relicved from'strains tending to separate the side members laterally. The vertical bodies of the transoins are flanged (.iut'fardiy at their endsnnd are conncetedtothe flanges of the transon'i-post's 1" by horizontal bolts 9, which extend parallel with the transombodies and are therefore in tension only, re-i sistingstralns tending tdspread the truck laterally, and not beingsubject to shearing strains.

- The side frame members are connected at their ends by transverse end braces 7, of angle-section, which are bolted both vertically and horizontally to the side frame members;

The wheels 4 are fixed upon axles 2, the

journals- 2 of which rotate in bearings in axle-boxes 3; which are fitted with the usual capacity of relative vertical movement be tween the members of each pair of )e' destaljaws 1. The weight carried by t e-truckframe is transmitted thereto through a bolster 10, the ends of which are supported on bolster-springs 5, resting on a spring-plank 6, which is suspended from the transoms by swing-hangers 8, and the Weight of the trucki'ramo and its load is carried by the axles through the intermediation of axle-box springs 3, hearing at their centers on the axle-boxes 3 and connected at their ends to the side members of the truck-frame by spring-han ers 3 Brakingi orce is applied. to the truck-wheels 4 through brake-shoes 12, which. at e suspended by hangers 13 from the top flanges of the trimsoms Q, said shoosibelnimtnnted by brahe-lsvors Zit, the lower on s of which on each side oil the times are coupled to'jaws 1 15 connected in. an ad usti rod or bar 16.

the jaws, abuts against the bar 16 and prevents the some from turning in-the jaws, except when it is caused to do so by the S PPl CBr tionof a wrench for the pur ose of maklb 5rdjustment of the distance etween the lower ends of the brahcicvers. in which operation the spring is i aised from its seat on the bar in the turning of the lottcr and resume-s its normal bearing on the bar when the wrench is removed. The j aws on opposite sides of the truck nrc connccted by cross-ties, which are coupled to lugs 18 on the jaws.

In order to properly support tho rnotols and prcvcnt undue wear, angular seats '22 are bolted to the outer sides of the vertical bodies of the tronsonis. and hardened-metal wearingplntc-s l9, on which the noses of the motors rest, as indicatml b dotted lines in Fig. 4,

- are fitted on the top lhmges of the trnnsoms and on said scats and are secured thereto by the bolts it). which connect the straps '21, which pass over the nosos of thomot-ors, no the trnnsoms.

The centers of the driving-gears 223, through which the truck-axles are rotated by the motors, are fixed upon or formed integral with inward extensions 4 of the wheel-hubs, or, if preferred. upon flanges extending inwardly from the webs of the wheels, and in order to increase the life of the gears their teeth are formed in separate rims 24. which are secured memorably on tlic ccnt crs, as by bring shrunk thereon in the same manner as tires. The

I rims arc formed oi hard steel similar to tircsteel and their centers Ofinz'lifil'ifil of computatively low cost, as cast-iron. The teeth or working portions of the gears may therefore llilllll. lllilllllll's, 21 1111115011] be renewed when worn or broken without the i necessitv oi substituting an entire new gear.
